wheel size for my 85?
 

Would like to change the stance with my 85. The wheels I have currently are stock pony wheels and a 225/55/16 tire. It has a Steeda suspension that the wheels and tires fit in nicely. Just want a change and not sure about my limitations. The susp.has been lowered but not alot. Can I get some suggestions from anyone? My avatar is the car Im talking about
